About the Event

Hosted by the Upper Arkansas Cooperative Weed Management Area (UACWMA), the Invasive Challenge 5K supports invasive species awareness and conservation efforts throughout the Upper Arkansas region.

The 2026 Encore offers another opportunity to participate and receive the same Russian olive medal featured in the original event. This is not a new medal design or the 2027 event.
